# python-libzim
`libzim` module allows you to read and write [ZIM
files](https://openzim.org) in Python. It provides a shallow python
interface on top of the [C++ `libzim` library](https://github.com/openzim/libzim).
It is primarily used in [openZIM](https://github.com/openzim/) scrapers like [`sotoki`](https://github.com/openzim/sotoki) or [`youtube2zim`](https://github.com/openzim/youtube).

## Installation
```sh
pip install libzim
```
The [PyPI package](https://pypi.org/project/libzim/) is available for x86_64 macOS and GNU/Linux only. It bundles a [recent release](http://download.openzim.org/release/libzim/) of the C++ libzim.
On other platforms, you'd have to [compile C++ libzim from
source](https://github.com/openzim/libzim) first then build this one, adjusting `LD_LIBRARY_PATH`.

## Usage
### Read a ZIM file
```python
from libzim.reader import Archive
from libzim.search import Query, Searcher
from libzim.suggestion import SuggestionSearcher
zim = Archive("test.zim")
print(f"Main entry is at {zim.main_entry.get_item().path}")
entry = zim.get_entry_by_path("home/fr")
print(f"Entry {entry.title} at {entry.path} is {entry.get_item().size}b.")
print(bytes(entry.get_item().content).decode("UTF-8"))
# searching using full-text index
search_string = "Welcome"
query = Query().set_query(search_string)
searcher = Searcher(zim)
search = searcher.search(query)
search_count = search.getEstimatedMatches()
print(f"there are {search_count} matches for {search_string}")
print(list(search.getResults(0, search_count)))
# accessing suggestions
search_string = "kiwix"
suggestion_searcher = SuggestionSearcher(zim)
suggestion = suggestion_searcher.suggest(search_string)
suggestion_count = suggestion.getEstimatedMatches()
print(f"there are {suggestion_count} matches for {search_string}")
print(list(suggestion.getResults(0, suggestion_count)))
```
### Write a ZIM file
```py
from libzim.writer import Creator, Item, StringProvider, FileProvider, Hint
class MyItem(Item):
def __init__(self, title, path, content = "", fpath = None):
super().__init__()
self.path = path
self.title = title
self.content = content
self.fpath = fpath
def get_path(self):
return self.path
def get_title(self):
return self.title
def get_mimetype(self):
return "text/html"
def get_contentprovider(self):
if self.fpath is not None:
return FileProvider(self.fpath)
return StringProvider(self.content)
def get_hints(self):
return {Hint.FRONT_ARTICLE: True}
content = """<html><head><meta charset="UTF-8"><title>Web Page Title</title></head>
<body><h1>Welcome to this ZIM</h1><p>Kiwix</p></body></html>"""
item = MyItem("Hello Kiwix", "home", content)
item2 = MyItem("Bonjour Kiwix", "home/fr", None, "home-fr.html")
with Creator("test.zim").config_indexing(True, "eng") as creator:
creator.set_mainpath("home")
creator.add_item(item)
creator.add_item(item2)
for name, value in {
"creator": "python-libzim",
"description": "Created in python",
"name": "my-zim",
"publisher": "You",
"title": "Test ZIM",
}.items():
creator.add_metadata(name.title(), value)
```
